Bug Description

opendkim crashes, probably on a malformed sender address:

Feb 18 16:01:55 gabriel-2 opendkim[972]: 1FEF4123A68: external host blade05.zfn.uni-bremen.de attempted to send as t-online..de
Feb 18 16:01:55 gabriel-2 postfix/cleanup[6445]: warning: milter inet:localhost:8891: can't read SMFIC_BODYEOB reply packet header: Success
Feb 18 16:01:55 gabriel-2 postfix/cleanup[6445]: 1FEF4123A68: milter-reject: END-OF-MESSAGE from blade05.zfn.uni-bremen.de[134.102.20.129]: 4.7.1 Service unavailable - try again later; from=<email address hidden> to=<email address hidden> proto=ESMTP helo=<blade05.zfn.uni-bremen.de>

Afterwards opendkim is gone:

Feb 18 16:01:55 gabriel-2 postfix/smtpd[2678]: warning: connect to Milter service inet:localhost:8891: Connection refused

My suspicion is that the two consecutive dots in 't-online..de' (see first line) cause the crash.

OS is Ubuntu 11.10 with updates applied. Opendkim is version 2.4.2+dfsg-0ubuntu1.

TEST CASE: Install the updated packages and verify correct operation from logs. Check logs for an instance of sequential dots in an email address. If opendkim didn't crash, this is fixed.

What's the output of opendkim -V on that system?

Also a copy of your /etc/opendkim.conf and /etc/default/opendkim would be helpful.

Nevermind on additional data. Upstream reports they've identified the issue and it's already fixed in the next version, 2.4.3.

That version is already in the development release of Ubuntu. I'll work with upstream and see how best we can get this fix into 11.10.

Uploaded the upstream change that was done for 2.4.3 in precise as a candidate post-release change for oneiric.

Thanks a lot for the quick response. The patch looks good so far and a few quick tests were successful. I will keep it running on one of our outgoing servers for a few days, then update the rest of the farm.

Great Christian. I'll consider that a "verification done". If you find any problems in the next 6 days, please report them immediately, as absent any reports of regressions, this will proceed to oneiric-updates on the 29th.
